Reservoir closure system and method

ABSTRACT

A system for sealably closing a reservoir is disclosed. The system can have a container and a slider. The container can have an orifice and catches and lips surrounding the orifice. The slider can be translatably attached to the container over the orifice. The slider can slidably engage the catch and lips to force the orifice closed. While attached to the catch and lips, the slider can create a pressurized seal of the orifice.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to the field of closeable and sealable fluidreservoirs. More specifically, this invention relates to reservoirs thatcan be closed and tightly and securely sealed, yet unsealed and openedrapidly.

2. Description of the Related Art

Light weight, resealable bags are used increasingly in sportingactivities, such as hiking, biking, and snow sport activities likeskiing and snowboarding. Limited access to the interior of typical bagsmakes cleaning more difficult and increases the potential for uncleanand unsanitary bags. Once liquids placed in the bags are consumed, theremaining deposits encourage the growth of bacteria and mold. If leftuncleaned, such growths can leave stains on the bag, may retain odors,taint any other fluids subsequently introduced into the bag, and createhealth risks. Regular and thorough cleaning of the inside of thereservoir is critical.

Commonly used bags for sporting are typically accessible through arelatively small side port in the bag, often covered by a removable cap.The side port limits the access to the interior of the bag, therebylimiting the ability to clean the interior of the bag.

Also, removing or adding large quantities of liquid to the typical bagsis often cumbersome and messy due to the limited and constrained accessto reservoir via the side port. The side ports can also limit the flowrate into and/or out of the bag, slowing the process of removing excessfluid from the bag or loading fluid into the bag.

Zipper-type closures have been developed for bags in some uses. Zipperclosures allow for larger and wider openings than typical side ports,thereby allowing easy cleaning of the interior of the bags. Zipperopenings also ease the process of removing and adding fluid to the bag,in speed, convenience and cleanliness. However, common zipper closuresare not suitable for most sporting activities. The bags often receiveforceful blows during regular use, causing large increases in fluidpressure inside the bag. Elements used to close the opening often needto be reinforced to ensure closure during use. For example, the caps onside ports are often threaded. However, zippers are often only a smallportion of the length of the entire opening, leaving much of the openingexposed to rupturing upon increased reservoir fluid pressure.

Roll-top closures satisfy the above demands: reinforced openings capableof withstanding high-pressure; ease of internal reservoir cleaning; andrapid, convenient, and clean liquid addition and removal. However, someusers feel that roll-top closures are cumbersome and slow to open andclose.

Therefore, a closeable reservoir system is desired that is capable ofease of internal reservoir cleaning. A closeable reservoir system isalso desired that can provide rapid, convenient and clean liquidaddition and removal. It is also desired to have a closeable reservoirsystem that can withstand significantly increased fluid pressureswithout leaking. A closeable reservoir system is also desired that iseasy and fast to open and close.

The slider can applypressure on the bag at any combination of the following areas: where theslider top contacts the lips and/or the catch; where the catches contactthe slider sides; where the slider arms contact the catches, where theslider arms contact the lips, and where the arms contact the guides.

The reservoir system can have side-catch gaps between the slider sidescan the corresponding catches. The reservoir system can have a top-catchgap between the slider top and the catches and/or lips. The reservoirsystem can have arm-catch gaps between the slider arms and thecorresponding catches. The reservoir system can have arm-lip gapsbetween the slider arms and the corresponding lips.

The arm and/or side compression forces can minimize and/orprevent fluid leakage from the reservoir out of the orifice.

When pressure in the bag increases (e.g., when the bag contains fluidand the bag is squeezed), the first and/or second catches can impair themovement of the slider first and/or second arms, respectively, in. anupward direction (with respect to the page of FIG. 10 a), for exampleretaining the slider on the bag.

The joint can be at theintersection of the slider top and the slider first and/or second side.The joint can enable the slider top to rotate with respect to the sliderfirst and/or second side. The joint can be fixable (e.g., lockable), forexample when the slider top is at a right angle with respect to theslider first and/or second side. The joint can be passive and/or biasedto force the slider top to a right angle with. respect to the sliderfirst and/or second side.

FIG. 13 illustrates that the slider of FIGS. 11 and 12 can be releasedand/or forcibly rotated, as shown by arrow. The slider first arm cansnap onto the first catch, fixedly attaching to the first catch bottomand/or producing the arm compression force. The slider first side can bedirectly adjacent to the first catch and/or producing the sidecompression force.

FIG. 14 illustrates that the orifice can be opened when the slider isnot engaged to seal the orifice. Compressive forces, as shown by arrows,can be applied to the ends of the lips. Tensile forces, not shown (butperpendicular to the shown compressive forces), can be applied to thesides of the lips. The first lip can separate from the second lip. Thelips can open in a puckered configuration. During use, solids and/orfluids (e.g., potable water, other beverages) can be transferred intoand/or out of the bag from the open orifice. The flexible bag can beturned inside out through the orifice, for example, to aid access andcleaning the inside of the bag. The lips can be configured to beresiliently biased to close.

The slider can be attached to the bag. For example, a leash can attachthe slider to the bag. The leash can be attached to the first and/orsecond hole. Also for example, the slider and/or bag can have a catchconfigured so the slider can not be completely slidably removed from thebag.
